Argus: Where Zeus has Aegis, Hera has Argus, its slightly nicer more public cousin agency. Named for the legendary watchmen, Argus is a public police and safety agency, with a peacock fan based badge. While Aegis has assumed a more public role at Argus' expense (indeed much of Argus' budget and many of its agents have been drafted into Aegis' ranks), Argus is a bit more popular on Jupiter for its role of protecting the public. The reality is more complex than that, since the agency frequently works hand in glove with Aegis on many matters, as well as Aegis current dominance over them.

Mamertines: Named for the old priests of Ares (or Mars), the Mamertines are the elite special forces of the Martian Legion. Ares gives them all of the difficult, dirty and deniable jobs of the Legion. Given their elite status they are very well trained and much better equipped than your typical Legionnaire.
